Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[mamiakimo]

Looks like it's by no means stable. Thermal cycling is hard on the works.

agreed. Looks like around a 20C swing for them. Mechanically that is not good for the chips and more specifically their solder bonds to the boards.

I just looked at my s9's and even the B17 and my latest a B18 (both never upgraded, has the auto-tune) is holding temps to about a 8-10C swing. I do see that the pre-auto tune ones with manual fan control have less variance, seems to be around 5-7C with my fans set to 85%.

In your screen shot I take it the gray-dotted trace and a couple others (~10C swing or less) are non-autotune miners?

all miners have the same firmware but this one is there new one that boards haven't same freq

[mamiakimo]

should i return to old firmware or what ?
they told me don't worry it's fine

[Biffa]

Both my batch 18's look like they might have a dead board in them after just 8 days use.  

Need to check when I get home

What pool?

Kano

Ends up there are no down boards, but the machine is clocking itself down to 7TH and one board is giving weird output numbers.

Going to try rebooting them one at a time see if that helps.

Different freq boards means it is autotune.
New stuff.
New firmware, new hardware controller.
I don't think the autotune s9 will work with old firmware, (pre autotune) but I have not tried it.

Kano is nice and smooth, should be good.
You may be able to send the dead board to Denver and they may fix it for $175+$25 shipping.
One of mine just arrived there now. You need a ticket at bitmainwarrany.com
Denver can walk you through troubleshooting first.

Lol yes I know I've been mining there since a few months after it started.

They aren't dead just acting wierd. bitmainwarranty is an option, depends what costs more, the last one I sent back to China worked out ok.

this version Antminer-S9-all-201611020159-autofreq-user.tar doesn't have this issue

1102 seems to run too hot. There is an 1108 version.

best one

[mamiakimo]

different between 3 versions

difference between 3 versions

This graph really highlights how much worse the fan profile is getting with each firmware release.

[not.you]

I would like to see one that can keep the temps under 100 without ramping up and down over and over again.  How hard could it be to set it up to make smaller speed adjustments when slowing and only do large adjustments when speeding up? If it's hot and you need it cool you need it to speed up quick but if it is cool you don't need it to drop from 100% all the way to 10% the way some of them do.  That's dumb.

EDIT: Or just give us manual control back...

Previous early batch s9 default freq 550/600, the hashboards have missing heatsinks (bitmain took out intentionally). If we update the new auto tune firmware s9, i think the boards will be too hot..so with the new auto tune s9 firmware, is it OK to update?

Reboot seemed to sort them out. Back to 11TH

[yesrno]

The S9 has been sold out for a while, any news on new batches?

Its only been sold out for 2 days. They released a new batch 2 days ago https://bitcointalk.org/index.php?topic=1493601.msg16810866#msg16810866 and they sold out in a couple of hours.

Sent another sick s9 board to denver , repair was $175+$25 to ship back.
One day turn around in denver.
Will be here in two days.
Excellent.

Ja. gotta love the ability to insure at full value + no concerns with Customs.

Now -- if we can only get Bitmain Warranty to tell us WHAT is failing on these boards! I asked them about it a couple time in email and is usually the same answer: "Well it means having the tech(s) record what they find and what is done to resolve it. That means someone (in Bitmain Warranty) has to enter the info in to logs and update the tickets with the information...."

In short - they won't do it because "it takes time and people.."
Riiiiight. Bet each tech has a daily work log of what they do eg. what Ticket#'s they work on, how many parts, when started, when done.. Bet *somewhere* in that work Ticket information is the diagnosis and resolution of problem. In other words: Fault(s) found and how repaired/why replaced. So why not lets us know?

Given what the repair cost runs, mine in the past have been around $140+ return shipping, Whatever is failing cannot be taking long to find/fix nor cost much if it a physical part that needs to be attended to. My company bills board/module (laser systems) repairs @ $115/hr + parts and based on that -- you get what I mean.

I think they check to see if it has any burns, if not you get a replacement from their stock.
Then yours gets sent to China for repair. Just my thoughts.
One day turn around? Hmmmm

I have picture of all boards I sent out and yes most maybe all of the times got different boards in return from both Bitmain with boards sent to them under RMA along with boards sent to BitmainWarranty for paid service.

Works for me. If the returned boards are reworks that were sent to China, also fine also long at it works and in fact, unless explicitly stated otherwise it is normal at least for industrial equipment industry-wide practice for Factory-Certified rebuilt replacements to be provided - even under Warranty Terms - when billable repair costs exceed value provided the mfgr/repair depot keeps the dead item (to be looked at elsewhere). If the final repair location can more economically fix the boards and put them back into the for Warranty repairs pool so be it.
